Abstract

Interactive Terminal Facility (ITF) is a program which allows users of S/36 asynchronous communications to connect to host applications and appear as an asynchronous ASCII terminal. ITF allows data from 5250 keyboard entry, test files, library members, or DisplayWrite/36 documents to be sent over an asynchronous communications line. Data received will be displayed at the 5250 terminal and may also be placed in a data file or library member. All ASCII control characters can be generated as well as a break signal. Typically, asynchronous ASCII terminals provide the capability to enter and receive data on the same line and to roll data up and off the screen. To accomplish these capabilities on a 5250 display, ITF provides 17 lines of an unformatted field followed by 2 lines (160 characters) of an input/output (I/O) field.
